WordPress 计数自定义帖子类型高级自定义字段

Question

我有 WordPress 网站和插件 Advanced Custom Fields，我为推荐创建了一个自定义帖子，里面是一个名为“ratings”的自定义字段，您可以在其中输入一个数字，例如1、3.5、5等

我想从每个帖子的字段中取出所有数字，然后将它们加起来为 5 的总数或平均值。

但是我很挣扎，我可以让它填充评级，例如5、5

但是我不能让它们加起来，有谁能帮忙吗？

这就是我到目前为止所拥有的......

<?php 
    $args = array( 'post_type' => 'testimonial', 'posts_per_page' => 9999 );
    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
?>
    <?php 
        $count = (get_field('rating'));
        print_r($count);
        $add = count($count);
        return $add;
        echo $add;
    ?>    
<?php
    endwhile;
?>  

Answer 1

尝试使用此代码。改了posts_per_page => -1

global $post;
$count = array(); // define $count as array variable
$args = array( 'post_type' => 'testimonial' 'posts_per_page' => -1, 'offset'=> 1);
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); 
   // push rating value inside the $count array
   $count[] = get_post_meta($post->ID, 'rating', true); 
endforeach; 
wp_reset_postdata();

$add = count($count);  // You can use this variable outside also.
echo $add;  // print total rating.

希望，这对你有帮助。谢谢。

他几乎做对了。只需将 count() 替换为 array_sum()

global $post;
$count = array(); // define $count as array variable
$args = array( 'post_type' => 'testimonial' 'posts_per_page' => -1, 'offset'=> 1);
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); 
   // push rating value inside the $count array
   $count[] = get_post_meta($post->ID, 'rating', true); 
endforeach; 
wp_reset_postdata();

$add = array_sum($count);  // You can use this variable outside also.
echo $add;  // print total rating.
echo $add/count($count) // Print average
